I am working on a script that asks for an input to be given between 1 and 100. I would like to have the restriction that the input is limited to between 1 and 100, and that the number must be a whole number.Here is the code:
number=input('Enter a whole number between 1 and 100:')
while number<1 || number>100
display('Not a valid number please try again')
number=input('Enter a whole number between 1 and 100:')
end
I can't figure out how to get it to set a restriction to non-whole number values. Please let me know how to specify this. I have been searching for a while and haven't found the solution.

Suprisingly, just run your specification and it works in MATLAB
number=input('Enter a whole number between 1 and 100:')
while number<1 || number>100
display('Not a valid number please try again')
number=input('Enter a whole number between 1 and 100:')
end

I would like to restrict the input to where if you put in a decimal value, ex. 4.5, the script will display Not a valid number please try again.

change to
while number<1 || number>100 || round(number)~=number

validateattributes( number, { 'numeric' }, { 'scalar', '>=', 1, '<=', 100, 'integer' } )
You would have to put a message together yourself though if you don't want the error message itself returned on command line
